>                 URL: https://issues.apache.org/jira/browse/IGNITE-9244
>             Project: Ignite
>          Issue Type: Bug
>         Environment: In the current implementation, GridDhtPartitionsEvictor reset partition
to evict one by one.
> GridDhtPartitionsEvictor is created for each cache group, if we try to evict too many
groups as sys pool size, group evictors will take all available threads in sys pool. It leads
to hangs send a message via sys pool. As a fix, I suggest to limit concurrent execution via
sys pool or use another pool for this purpose.
